Moran Flies for the Prize Do all fruit flies look identical? Perhaps some have larger wings, darker color, white or red eyes? True, fruit flies are tiny, but if you ask Thomas Hunt Morgan, he would know. Nobel Prize wining scientist Thomas Hunt Morgan was born on September 25,1866, in Lexington, Kentucky. He graduated from State College ( now the University of Kentucky) and received a doctorate from John Hopkins University in Baltimore. In 1904, as a professor of Experimental Zoology at Columbia University, Dr. Morgan began the research into heredity that would later earn him worldwide acclaim. In 1933, he was awarded the Nobel Prize in medicine, the first one ever given to a non-physician. Fascinated by Gregor Mendel's studies in pea heredity, Morgan wanted to know more about how traits of the parent are passed to their offspring. Since the common fruit fly produces over thirty generations per year it was ideal for Morgan's studies. By crossbreeding, inbreeding,and backbreeding thousands of flies and carefully observing the traits passed from generation to generation, Morgan and his colleagues formed the Chromosome Theory of Heredity. This theory is the basis for a branch of biology called Genetics. Genetics

[GENETICS]. MORGAN, Thomas Hunt A collection of eighty-seven (87) of Morgan's papers on evolution, biology and genetics, especially heredity and cytology in relation to sex determination as well as embryology and its relations to heredity. Morgan (1866-1945), best-known for his discovery of the mechanism by which sex is determined at the instant of the egg's fertilization (XX or XY chromosomes), was a celebrated embryologist, zoologist and geneticist. He was awarded the 1933 Nobel Prize in Medicine for establishing the chromosome theory of heredity. All of the offprints are from the libraries of L.C. Dunn, Edmund B. Wilson, Karl Sax and E.M. East.

Han og hans “flue-forskergruppe” skabte en enorm basisviden, som ligger til grund for vores forståelse af den rolle, kromosomer og gener spiller for arvelighed. Thomas Hunt Morgan blev født i Lexington, Kentucky i USA. Han afsluttede sin naturvidenskabelige uddannelse på State University of Kentucky. I 1886 tog han til Johns Hopkins University for at studere zoologi. Her afsluttede han sin doktorafhandling om fosterudvikling hos havedderkopper. I 1904 blev han inviteret til Columbia University af sin gode ven Edmund Wilson. Her blev han ansat som lærer i eksperimentel biologi. Det var på Columbia University, at Thomas Hunt Morgan tog hul på “babanflue-kapitlet” i sit liv. Morgan var blevet interesseret i variationer inden for arter, og i 1911 etablerede han “flue-laboratoriet” på Columbia. Målet var at undersøge, hvordan arter ændrer sig over tid. I de næste 17 år udførte Morgan og hans studerende helt grundlæggende forskning på bananfluer - Drosophila melanogaster. Det foregik i et lille lokale på bare omkring 5x7 meter, som mange omtale som trangt, støvet, ildelugtende og hjemsøgt af kakkerlakker. Oprindelig var Morgan modstander af ideen om, at det skulle være kromosomerne, der bestemmer arvelighed. Men han blev snart den førende fortaler for samme idé. Morgan og hans studerende Alfred Sturtevant, Calvin Bridges, Hermann Muller og flere andre udviklede ideerne og leverede beviset for kromosomernes betydning i arvelighed, koblede gener, overkrydsning blandt kromosomer og non-disjunction.

Home About Topics Subscribe ... Introduction Thomas Hunt Morgan Thomas Hunt Morgan, an embryologist who had turned to research in heredity, in 1907 began to extensively breed the common fruit fly, Drosophila melanogaster . He hoped to discover large-scale mutations that would represent the emergence of new species. As it turned out, Morgan confirmed Mendelian laws of inheritance and the hypothesis that genes are located on chromosomes. He thereby inaugurated classical experimental genetics. After breeding millions of Drosophila in his laboratory at Columbia University, in 1910 Morgan noticed one fruit fly with a distinctive characteristic: white eyes instead of red. He isolated this specimen and mated it to an ordinary red-eyed fly. Although the first generation of 1,237 offspring was all red-eyed but for three, white-eyed flies appeared in larger numbers in the second generation. Surprisingly, all white-eyed flies were male. These results were suggestive for hypotheses of which Morgan himself was skeptical. He was at the time critical of the Mendelian theory of inheritance, mistrusted aspects of chromosomal theory, and did not believe that Darwin's concept of natural selection could account for the emergence of new species. But Morgan's discoveries with white- and red-eyed flies led him to reconsider each of these hypotheses.

After studying zoology at Freiburg and Munich, he received his doctorate at Jena in 1889 for work under Ernst Haeckel on coelenterates. Through a series of major monographs including Analytische Theorie der Organischen Entwicklung Die Seele als Elementare Naturfaktor (1903), and History and Theory of Vitalism (1905), Driesch developed a unqiue "biotheoretical" approach to organismal study, incorporating mathematical analysis of organismal structures in a strongly teleological vitalist framework that he called entelechy. He remained an antimaterialist throughout his career.

University of California, Berkeley. Department of Genetics Collection (0.5 linear feet) American Philosophical Society 105 South Fifth Street * Philadelphia, PA 19106-3386 Table of contents Abstract In 1912, the University of California, Berkeley, became the first university in the nation to form a separate Department of Genetics. The first two appointments in the department went to plant geneticists Ernest Brown Babcock and Roy E. Clausen, and as the department grew slowly, shifting slightly away from its roots in agricultural science, it gained a strong reputation as an important center for research in several areas in genetics and evolutionary biology. The U.C. Berkeley Department of Genetics Collection contains a selective sampling of correspondence relating to the organization and early history of the nation's first Department of Genetics. Centered in the years 1912-1930, the collection consists primarily of correspondence to and from Babcock and Clausen, pertaining to their research, administrative matters, and the genetical community. Prominent among their correspondents are George H. Shull, Thomas Hunt Morgan, A. H. Sturtevant, and H. J. Muller. Background note Scope and content Administrative information Restrictions on use ...

Nakon studija prirodnih znanosti na sveuèili¹tu Johnn Hopkins u Baltimoru, gdje je 1890. godine doktorirao filozofiju, bio je asistent i profesor biologije na Bryn Mawr Colledgeu, a 1904. imenovan je profesorom eksperimentalne zoologije na sveuèili¹tu Columbia u New Yorku. Ondje i poèeo eksperimentalna istra¾ivanja mehanizma naslijeða. Od 1928. do smrti bio je direktor laboratorija za biolo¹ke znanosti u kalifornijskom Tehnolo¹kom institutu u Pasadeni. Godine 1933. Morgan je dobio Nobelovu nagradu za otkriæe u vezi s funkcijom kromosoma u preno¹enju nasljednih svojstva . Izradio je i prve karte polo¾aja gena u kromosomima, a u znanosti ga smatraju glavnim predstavnikom kromosomne teorije heriditeta. Zajedno sa svojim uèenicima Morgan je razradio slo¾enu teoriju o genima kao materijalnim nositeljima nasljednih osobina.
